SMS Spam Checklist

Ensure your SMS marketing complies with best practices and avoids spam filters.

Follow these do's and don'ts to improve deliverability and maintain a good sender reputation.

Consent & Compliance

Obtain explicit opt-in consent from recipients.

Provide a clear way to opt-out (e.g., "STOP").

Identify yourself or your business clearly.

Buy lists of phone numbers from third parties.

Use standard grammar and spelling.

Keep messages concise and relevant.

Use aggressive capitalization (e.g., "FREE MONEY NOW").

Use public URL shorteners (bit.ly, tinyurl) which are often flagged.

Send messages during reasonable waking hours.

Stick to the frequency you promised during opt-in.

Send high volumes of messages from a new number immediately.

Sheet SMS is the #1 add-on for sending text messages, scheduling campaigns, and managing conversations without leaving your spreadsheet.
